A pool starts with 10,000 gallons of water in it. A hose can be used to fill the pool at a constant rate of 9 gallons per minute. A drain in the pool can empty the pool at a constant rate of 9 gallons per minute. The expressions below can be used to determine how much water is in the pool after 20 minutes. 10,000 + 20 -9 What does each expression represent in the context of this situation? Explain how you know.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction
